similar to: unable to access index for repository...

Thanks for the help. I do update to the latest R-4.0.2. As I said, for reasons that's hard to explain, some of my tasks are better handled with an older version of R, in this case R-3.0.3. Please just help me install packages successfully with this older version of R. I ran the following line but obviously was not getting it across. ===== >

He didn't specify the RStudio repos, though it's probably implicitly specified in getOption("repos"). I wonder why install.packages() is looking there, when repos is given explicitly?

Thanks. You gentlemen please tell me what this means. In R (outside of RStudio) I ran: install.packages("aod") Received a warning (and installation did not seem to go through). Then I tried install.packages("aod",repos='https://cran-archive.r-project.org') Received a warning but it went on to try

Then you'd rather need install.packages("aod",repos='https://cran-archive.r-project.org') or use the contrib.url argument.

Drop the RStudio repos. Best, Uwe Ligges On 05.10.2020 11:10, Steven Yen wrote: > Thanks. I did as suggested but still received a warning, though the > installation went through.

Sorry Gentlemen and all. Now this is becoming a joke (to me). I repeated what I did earlier, with and without the option to set repos suggested by Duncan. Now it does not work. I wonder whether it is dependent on the mirror I chose, but I do not remember the one I chose earlier when it work. I need your help, gentlemen, as I need to use R-3.0.3 for my task. >

Just remembered: RStudio runs its own wrapper around install.packages(). Steven, you should try doing the install from outside of RStudio, and see if it makes a difference.

Okay, so it's not an RStudio issue. However, I'd guess setting options(repos = "https://cran-archive.r-project.org") at the start of your session could make everything work. (I'm guessing you currently have it set to "http://cran.rstudio.com", which is the source of the last warning below, probably due to an R bug. But since you're using an obsolete

From ../ReadMe in the mentioned web resource: "Packages for R >= 1.7.0 and R < 3.2.0 are available from https://cran-archive.r-project.org/bin/windows/contrib/" We do not hold binaries of several year old versions of R on CRAN. Note that R 3.0.0 is 7 years old. You shoudl realy consider to update to 4.0.2. Best, Uwe Ligges On 05.10.2020 09:56, Steven Yen wrote: > I had

Thanks for the help. I have a reason to continue with R-3.0.3. I used maxLik to estimate econometric models and some of them are better handled with R-3.0.3 (but not later)----a sad reality I do not like. Here is what I did. I downloaded https://cran-archive.r-project.org/bin/windows/contrib/3.0/aod_1.3.zip and installed the zip file, which worked in both RStudio and R (without RStudio). In

Don't choose a mirror. That will override the repos choice. Do update R to a current version if you aren't able to debug this yourself.

All support on this list is voluntary, and support for old versions of R is not even necessarily on-topic here which is why you keep getting nudged to upgrade. Your "need" for support for an old version is definitely not "our" problem, so I suggest you start looking for a consultant if this issue is that important to you. Such is the nature of volunteer-developed open source

I wonder if you are perhaps trying to solve the wrong problem. If you like what the older version of the aod package does, but not the current version, then I think the solution is to propose an option to the aod maintainer that would restore your preferred algorithm into the current version, and then use the current R. A less good, but possibly workable, option is to compile the old version of

Hmm. You raised an interesting point. Actually I am not having problems with aod per se?-it is just a supporting package I need while using old R. The essential package I need, maxLik, simply works better under R-3.0.3, for reason I do not understand?specifically the numerical gradients of the likelihood function are not evaluated as accurately in newer versions of R in my experience, which is why

Hi Steven Which optimisation algorithms in maxLik work better under R-3.0.3 than under the current version of R? /Arne On Thu, 8 Oct 2020 at 21:05, Steven Yen <styen at ntu.edu.tw> wrote: > > Hmm.

Oh Hi Arne, You may recall we visited with this before. I do not believe the problem is algorithm specific. The algorithms I use the most often are BFGS and BHHH (or maxBFGS and maxBHHH). For simple econometric models such as probit, Tobit, and evening sample selection models, old and new versions of R work equally well (I write my own programs and do not use ones from AER or sampleSekection).

Though Navigator may mess up any Rtools stuff because it handles the directory trees where packages and dependencies are located, does it not? If so, maybe just reinstall RStudio directly from its website to proceed. Just a guess obviously.

Dear all; I found a useful video on youtube that has explained how to install Rtools. I followed the instructions and the problem was solved.
